Abstract:
:We evaluated the effects of repeated subanesthetic ketamine infusions on suicidal ideation (SI) in patients with major depression. 82 subjects with treatment-resistant unipolar and bipolar depression completed a two-site open-label case-series of repeated (up to four weeks) infusions of ketamine (0.5 mg/kg). Ketamine produced a significant reduction in SI as early as one hour (71.1%) and up to 1-week post-infusion (60.4%), accompanied by a reduction in overall depressive symptoms which were maintained until the 4th week. The observed anti-suicidal effect was independent of mood changes, as patients whose mood did not respond still exhibited significantly less SI than baseline.
